What Is Gluconolactone?
Gluconolactone is a dry powder that can be used in cosmetics as a skin conditioner and to help control pH levels. It's also used as a food additive for its acidic properties and ability to bind with minerals. Gluconolactone has no smell and appears as fine, white crystals or solid form. Another name for it is delta-gluconolactone.
What is the purpose of Gluconolactone in personal care products?
It is used for its chelating
and skin conditioning characteristics.
Gluconolactone prevents ingredient degradation and moisturizes and strengthens skin.
What Are Chelating Ingredients?
Gluconolactone has chelating characteristics.
Chelating ingredients in cosmetic products help maintain the product's effectiveness and stability by preventing degradation. They work by binding to metal ions, such as calcium, magnesium, and iron, that can be present in the water used to make the product or that may be present on the skin.
These metal ions can cause the cosmetic product to deteriorate over time, leading to color, texture, and odor changes. Chelating ingredients help to prevent this by capturing the metal ions and preventing them from reacting with the other ingredients in the product.
In addition, chelating ingredients can help enhance preservatives' effectiveness by preventing them from being deactivated by metal ions.
Chelating Ingredients in Other Products
Chelating ingredients can be used in food and beverages to control metal ions affecting taste, color, and texture. For example, they stabilize colors in canned fruits and vegetables and prevent oxidation in wine.
Chelating agents are used in pharmaceutical products to help improve their stability and shelf life. They can help to prevent metal-catalyzed degradation and enhance the effectiveness of certain drugs.
Types of Chelating Ingredients
Here are some of the most common types of chelating ingredients:
Amino acids and peptides: These compounds contain functional groups that can form coordination bonds with metal ions, such as carboxylic acid and amine groups.
Polycarboxylic acids: These are complex organic acids with multiple carboxylic acid functional groups that can form strong chelating complexes with metal ions.
Organic acids: These include citric acid, acetic acid, and oxalic acid, which can form chelating complexes with metal ions.
Sugars and sugar acids: These include compounds such as glucose, fructose, and gluconic acid, which can form chelating complexes with metal ions.
Polyamines: These are organic compounds with multiple amine functional groups that can form coordination bonds with metal ions.
Hydroxycarboxylic acids: These include compounds such as gluconic acid and tartaric acid, which can form chelating complexes with metal ions.
Sulfonic acids: These are organic acids containing functional groups that can form chelating complexes with metal ions.
Phosphates: These include compounds such as phosphoric acid, which can form chelating complexes with metal ions.
What Are Skin Conditioning Ingredients?
Gluconolactone has skin conditioning characteristics.
Skin conditioning ingredients improve the texture, feel, and overall appearance of the skin, helping to avoid harmful effects from external factors. Skin conditioning ingredients moisturize the skin and strengthen its natural barrier function to help protect it from damage caused by harsh weather and sunlight. Some skin conditioning ingredients are anti-inflammatory and can help reduce redness and irritated skin.
